    Default 2017 Mojo with Raptor 400 misfiring

    My engine lost power and began vibrating while under load on multiple occasions (surfing and take off). The dealer worked with Indmar during the 20 hr initial service and determined from the engine log that it was misfiring on the lower 8 plugs. They were told to remove the aluminum heat shields around the plugs wire to prevent arcing. Had it out today and no issues.
